SHUTTLE-BINDER FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 373,896, datedNovember 29, 1887.

Application filed Man-117, 1887.

looms, and to that class thereof which are pivoted; and the invention consists in the peculiar construction and arrangement ofthe binder and of the several parts thereof, all as hereinafter fully described, and pointed out in the claim.

In the drawings forming part of this specification, Figure 1 is aperspective view of an ordinary loom shuttle-box having applied thereto ashuttle-binder embodying myimprovements. Fig. 2 is a side elevation of a portion of the binder. Fig. 3 is a longitudinal section of that part of the binder shown in Fig. 2, showing, in dotted lines,one position of the'hinged end of the binder.

This invention is in the nature of an improve nent upon the construction shown and described in Letters Patent issued to me January 9, 1883, No. 270,228,the object of the herein-described improvements being to provide an improved hinge-connection between the body of the binder and the piece which is connected to its free end, whereby said piece is capable of vibrating from as well as toward the shuttle, and whereby the said hinged piece is capable of such adjustmentwith relation to its operating-spring as cannot be easily deranged by those working on a loom to which the binder is attached.

A further object of the improved construction herein shown is to provide a simplified hinged connection between the binder and its said hinged end-piece.

In the drawings, 3 indicates the shuttle-box of aloom, and 4 the shuttle-binder, which is pivotally connected by one end at n to the shuttle-box, whereby the binder is capable of a certain vibratory motion in a horizontal plane. The said binder is constructed, preferably, of malleable iron,to obviate the danger of breakage in the useto which it is subjected. A spring, 6, is attached. by one end to the side of the shuttle-box, as shown, and its free end prevented from turning in said socket.

box for a certain time.

has a bearing against the side of the binder, whereby the latter is held yielding-1y in a certain position opposite the vertical side of the ShUDLlEbOX.

The free end of the binder 4 is slotted, as shown, to permit of the introduction between its bifurcated parts of the end of the hinged extension-piece c, a pivot-pin, 00, being passed transversely through said bifurcated parts and the end of said piece 0, whereby the latter is hinged or pivoted to the end of the binder,the latter having formed therein a socket, e. The socket e is adapted to receive a spiral spring, 0, one end of which bears against the base of said socket, and a plunger, o, having one end cylindrical, is placed Within said spring, the outer end of the latter bearing against a shoulder on said plunger, as shown. The outer end of the plunger o, as well as the end of the socket e, in which it operates, are of rectangular form, in order that the plunger may be The face of the outer end of theplunger o is at right angles to its axis, and the end of the aforesaid hinged extension-piece 0, against which the end of said plunger is forced by said spring 0, is at right angles to its inner face, so that the normal position of said hinged piece 0, when solely under the control of the plunger 12 and the spring 0, is that shown in the drawings, the dotted lines in Fig. 3 showing the position of said hinged piece when swung toward the vertical side of the shuttle-box. lVhen the hinged extension-piece c is struck by a moving part, a, Fig. 1, of the loo1n,whereby it is swung toward the vertical side of the shuttle-box, acertain resistance to said swinging movement of said piece a is supplied by the spring othrough the plunger o,which is driven endwise against said spring by the engagement of the end of the piece c with the end of said plunger, and the degree of resistance which said spring offers to the deflection of the hinged extensionc toward the shuttle 5, when the latter is between the binder and the opposite side of the shuttie-box, determines the retaining force of the binder to keep the shuttle in its place in the In constructing the binder and connecting thereto its said hinged extension-piece the desired strength of the spring 0 is definitely fixed upon, and after it is inserted in the socket in the binder,together with the plunger 7), and the piece a is secured to the end of the binder by the pin x,which is riveted lhereto,the parts mn'streinain in their operative relations,thereby insu ring the action of the said extension-piece 0 under a regulated resistance, a derangement of said parts being difficult owing to the permanency ot'their coir nection, as ahovedescribcd,whereas in my said patent a loonroperative might, to the detriment of the proper operation ot the device, change the resistance to the vibratory-move nient of the extension-piece of the binder by turning the nuton the end of the boltf ofsaid patent.

I have found in practice that for the better protection of the binder against injury by loom-operatives it is advisable to provide a hinged connection between the extensionpieee sand the body of the binder, which permits said extension-piece to swing outwardly or away from the shuttle box as well as toward it, for the reason that said operatives, under the impression that the binder should, for some reason, be curved more than it ordil l l l l i l l l l i I l l i I l l l l l l l l narily is toward the shuttle, attempt to bend the binder by striking it when the shuttle or some other object is between the extensionpiece 0 and the oppositeside of the shuttle-box; and it said extension-piece, under those circumstances, is rigid against any outward movement, as it is in my said patent, itS hinged connection with the binder is likely to be broken or rendered inoperative, whereas, by means 01' the construction herein shown, any injury to the binder parts by such treatment is obviated.

\Vhat I claim as my invention is- A shuttle-binder for looms,having a socket, c, in its'lree end,combined \viththe extensionpiece a, hinged to the end of the binder and capable of vibratory motions thereon, the spring 0 within said socket, and the plunger 11, entering said spring and having its end engaging the hinged end of said piece 0, substantially as set forth.
